So I find my "squeal" in the rear is due to the inboard pad being down to the base plate (nice, I know) and the store tells me there is a choice of large or small clips on the rear pads...I tell him theres really no way for me to tell since I only have "one size" here to tell from and he's none in the store to compare mine to so they must be ordered. Anyone know why there is a differance and how I can tell? Thanks in advance.
